TECHNICAL FIELD

The present disclosure generally relates to data management, and more specifically, relates to systems and methods for transmitting data efficiently.

BACKGROUND

In some occasions, it is necessary and/or desirable to efficiently send data to remote locations, especially when the data is requested by users (e.g., back end engineers). For example, when problems arise in an autonomous vehicle testing, and these problems need to be analyzed quickly and efficiently, often requiring remote data transfer. In essence, before the back end engineers can analyze the problems, they need the data, at least the relevant data, in the autonomous vehicle properly transferred to them. The overall data generated during operation of the autonomous vehicle is generally very large (e.g., the file size of all the data may reach 1G in several minutes). However, there is usually only poor mobile network in and around the autonomous vehicle, making it difficult to send all the data related to the autonomous vehicle to remote engineers. Therefore, it is desirable to provide systems and methods that can efficiently and safely transmit requested data to remote engineers.

It is necessary and/or desirable to efficiently and safely send remote data to users (e.g., back end engineers) to quickly solve the problems arising during the operation of an autonomous vehicle. To this end, systems and methods for data management for an autonomous vehicle in the present disclosure may transmit a polling request to a first server to obtain a task, wherein the task is a remote task request, and the task is associated with obtaining, from the autonomous vehicle, requested data related to one or more subjects (not overall data generated by the autonomous vehicle) via a mobile network. The systems and methods may receive the task from the first server based on the polling request. The systems and methods may obtain the requested data based on the task. The systems and methods may transmit the data to a file server via the mobile network.

The systems and methods for data management in the present disclosure may efficiently and safely and remotely transmit the requested data because the systems and methods pulls a task from the first server based on a polling request and transmit the requested data based on the task, instead of users actively accessing the autonomous vehicle to obtain the requested data through a virtual private network (VPN), and because the requested data may be transmit to the file server via a mobile network in the autonomous vehicle a relatively short time after the task is transmitted to the first server, instead of waiting for more than 1 week to get the requested data by delivery.

In some embodiments, the communication port 240 may be and/or include a standardized communication port, such as RS232, RS485, etc.

FIG. 3 is a schematic diagram illustrating exemplary hardware and/or software components of a mobile device on which the user terminal 140 may be implemented according to some embodiments of the present disclosure. As illustrated in FIG. 3, the mobile device 300 may include a communication platform 310, a display 320, a graphic processing unit (GPU) 330, a central processing unit (CPU) 340, an I/O 350, a memory 360, and a storage 390. In some embodiments, any other suitable component, including but not limited to a system bus or a controller (not shown), may also be included in the mobile device 300. In some embodiments, a mobile operating system 370 (e.g., iOS™, Android™, Windows Phone™, etc.) and one or more applications 380 may be loaded into the memory 360 from the storage 390 in order to be executed by the CPU 340. The applications 380 may include a browser or any other suitable mobile apps for receiving and rendering information relating to the data management system 100 or other information from the processing engine 112. User interactions with the information stream may be achieved via the I/O 350 and provided to the processing engine 112 and/or other components of the data management system 100 via the network 120. Merely by way of example, the state of a task may be displayed in the user terminal 140 through the display 320. As another example, a user may input a task through the I/O 350.

To implement various modules, units, and their functionalities described in the present disclosure, computer hardware platforms may be used as the hardware platform(s) for one or more of the elements described herein. A computer with user interface elements may be used to implement a personal computer (PC) or any other type of work station or terminal device. A computer may also act as a server if appropriately programmed.

One of ordinary skill in the art would understand that when an element of the data management system 100 performs, the element may perform through electrical signals and/or electromagnetic signals. For example, when the controller 132 processes a task, such as making a determination, or identifying information, the controller 132 may operate logic circuits in its processor to process such task. When the controller 132 receives data (e.g., a remote task) from the processing engine 112, a processor of the controller 132 may receive electrical signals encoding/including the data. The processor of the controller 132 may receive the electrical signals through one or more information exchange ports. If the processing engine 112 communicates with the controller 132 via a wired network, the information exchange port may be physically connected to a cable. If the processing engine 112communicates with the controller 132 via a wireless network, the information exchange port of the controller 132 may be one or more antennas, which may convert the electrical signals to electromagnetic signals. Within an electronic device, such as the controller 132, the user terminal 140, and/or the server 110, when a processor thereof processes an instruction, sends out an instruction, and/or performs an action, the instruction and/or action is conducted via electrical signals. For example, when the processor retrieves or saves data from a storage medium (e.g., the storage device 180), it may send out electrical signals to a read/write device of the storage medium, which may read or write structured data in the storage medium. The structured data may be transmitted to the processor in the form of electrical signals via a bus of the electronic device. Here, an electrical signal may refer to one electrical signal, a series of electrical signals, and/or a plurality of discrete electrical signals.

FIG. 4 is a schematic block diagram illustrating an exemplary controller for an autonomous vehicle according to some embodiments of the present disclosure. The controller 132 may include a polling module 410, a task receiving module 420, a data collection module 430, and a transmission module 440.

The polling module 410 may be configured to transmit a polling request to the server 110 to pull a task from the server 110. The task may be a remote task request. The task may be associated with obtaining, from the autonomous vehicle 130, requested data related to one or more subjects via a mobile network.

In some embodiments, the overall data set generated during the operation of the autonomous vehicle 130 may be too big to be transmitted via a mobile network. In order to obtain data related to the autonomous vehicle 130 via the mobile network, a task related to obtaining a part of the overall data (e.g., relevant and/or requested data) may be initiated.

In some embodiments, the task may include the one or more subjects and a duration of the requested data. In some embodiments, the subject may include data sources (e.g., which sensor in the autonomous vehicle 130 collects the data), the purpose of data (e.g., the data is used to detect traffic lights, the data indicates the speed of the autonomous vehicle 130), data types (e.g., text, sound, video, image, etc.), or the like, or any combination thereof. In some embodiments, the duration may be any prior time period or any future time period. For example, the start time or the end time of the duration may be a prior time point, a current time point (e.g., the time when the task is transmitted to the server 110), or a future time point.

In some embodiments, when one or more specific conditions happen, the transmission module 440 may automatically transmit a task to the server 110. For example, when the controller 132 automatically reports an error related to one or more operational issues of the autonomous vehicle 130, the transmission module 440 may automatically transmit a task to the server 110. Merely by way of example, when the controller 132 automatically reports an error related to detecting traffic lights, the transmission module 440 may automatically transmit, to the server 110, a task including one or more subjects related to detecting traffic lights and a duration of last three days. As another example, when a driver or a test engineer manually inputs an error message related to one or more operational issues of the autonomous vehicle 130 through the controller 132 (e.g., the I/O 230 of the controller 132), the transmission module 440 may automatically transmit a task to the server 110. Merely by way of example, when a driver or a test engineer finds that the autonomous vehicle 130 make a mistake for detecting traffic lights, the driver or a test engineer may manually input an error message related to detecting traffic lights through the controller 132. The transmission module 440 may automatically transmit, to the server 110, a task including one or more subjects related to detecting traffic lights and a duration of last three days.

In some embodiments, a user (e.g., a back end engineer) may input a task through the user terminal 140. The user terminal 140 may transmit the task to the server 110. For example, if the user wants to analyze the detection of traffic lights of the autonomous vehicle 130 last three days, the user may input, through the user terminal 140, a task including one or more subjects related to detecting traffic lights and a duration of last three days.

In some embodiments, when receiving a task, the server 110 may store the task information (e.g., the one or more subjects and the duration) of the task in the database server 160.

In some embodiments, the polling module 410 may transmit the polling request to the server 110 continuously or at intervals (e.g., every 10 seconds, every 20 seconds, etc.). In some embodiments, the polling module 410 may transmit the polling request to the server 110 when the controller 132 processes no task.

In some embodiments, considering the safety of the autonomous vehicle 130, the process for obtaining requested data based on the task would be configured so that it would not affect other operations (e.g., the operations for controlling the movement of the autonomous vehicle 130) performed by the controller 132. As a result, the polling module 410 may transmit the polling request when the autonomous vehicle 130 is in a non-autonomous driving mode (e.g., a manual driving mode or a non-operating mode).

The task receiving module 420 may be configured to receive a task from the server 110 based on the polling request.

In some embodiments, in the server 110, the tasks from the autonomous vehicle 130 and/or the user terminal 140 may be arranged in a queue in chronological order of being received by the server 110. In some embodiments, for security, the active access of the server 110 to the autonomous vehicle 130 may not be allowed. Therefore, the polling module 410 may transmit a polling request to the server 110. When receiving the polling request from the polling module 410, the server 110 may transmit the first task in the queue to the task receiving module 420 in response to the polling request.

In some embodiment, when receiving a polling request from the controller 132, the server 110 may determine whether there is a task that is being processed by the controller 132 based on, for example, the state of the task. In response to a determination that there is no task that is being processed by the controller 132, the server 110 may transmit the first task in the queue to the task receiving module 420. In response to a determination that there is a task that is being processed by the controller 132, the server 110 may not transmit any task to the task receiving module 420.

The collection module 430 may be configured to obtain the requested data based on the task.

In some embodiments, the autonomous vehicle 130 may generate a large amount of original data (e.g., the size of the original data may reach 1G in several minutes) during the operation of the autonomous vehicle 130. The large amount of original data may be stored in a storage medium (e.g., the storage device 180, and/or the storage 220 of the controller 132) of the autonomous vehicle 130.

The original data generated during the operation of the autonomous vehicle 130 may be marked with one or more subjects and a timestamp. The collection module 430 may collect the requested data by comparing the subject in the task with the subject of the original data and comparing the duration in the task with the timestamp of the original data.

In some embodiments, if the end time of the duration in the task is a future time point, the collection module 430 may wait for the future time point to obtain the requested data.

In some embodiments, the collection module 430 may further process the collected data. Merely by way of example, the collection module 430 may compress the collected data (e.g., images and/or videos) that is from computer vision (e.g., cameras) in the autonomous vehicle 130. In some embodiments, the processing instruction may be included in the controller 130. For example, after collecting the original data based on the task, the collection module 430 may automatically perform the compression instructions to compress the collected data (e.g., images and/or videos) that is from computer vision (e.g., cameras). In some embodiments, the task may include the processing instructions. For example, after collecting the original data based on the task, the collection module 430 may compress the collected data (e.g., images and/or videos) that is from computer vision (e.g., cameras) based on the compression instructions in the task.

The transmission module 440 may be configured to transmit the requested data to the file server 170 via the mobile network. In some embodiments, after receiving the requested data from the autonomous vehicle 130, the file server 170 may transmit the storage location of the requested data to the server 110. Alternatively, after receiving the requested data from the autonomous vehicle 130, the file server 170 may transmit the storage location of the requested data to the controller 132 (e.g., the transmission module 440). The controller 132 (e.g., the transmission module 440) may transmit the storage location to the server 110. The server 110 may transmit the storage location of the requested data to the user terminal 140, directing the user terminal 140 to display the storage location. The server 110 may transmit the storage location of the requested data to the user terminal 140, directing the user terminal 140 to display the storage location.

In some embodiments, the file server 170 may permanently store the requested data. In some embodiments, the file server 170 may delete the requested data after a period of time (e.g., 1 week, 2 weeks, 1 month, etc.).

In some embodiments, the server 110 may update the state of the task based on the condition the task is in. The state of the task may include a state of waiting, a state of running, a state of done, and a state of error. The state of waiting indicates that the task is waiting for being processed by the controller 132 in the server 110. The state of running indicates that the task is being processed by the controller 132. The state of error indicates that there are one or more errors during processing the task and the process for processing the task is terminated. The state of done indicates that the task has been done by the controller 132 (e.g., the transmission module 440 has transmitted the requested data to the file server 170).

In some embodiments, the transmission module 440 may transmit the state of the task to the server 110 during the collection of the data. For example, because the requested data is transmitted through a mobile network, there may be a limitation to the size of the requested data. If the size of the requested data is larger than a size threshold (e.g., 10M, 20M, 30M, 50M, etc.), the transmission module 440 may transmit a message indicating that the task is in the state of error to the server 110. The server 110 may update the task state to the state of error based on the message. As another example, if the duration for obtaining the requested data is longer than a duration threshold (e.g., 10 s, 20 s, 30 s, etc.), the transmission module 440 may transmit a message indicating that the task is in the state of error to the server 110. The server 110 may update the task state to the state of error based on the message. As still another example, when the transmission module 440 transmits the requested data to the file server 170, the transmission module 440 may transmit a message indicating that the task is in the state of done to the server 110. The server 110 may update the task state to the state of done based on the message. As further another example, when the transmission module 440 does not transmit, to the server 110, a message indicating the state of the task (e.g., the state of error or the state of done) during the obtaining of the requested data in a predetermined period of time (e.g., 30 s, 40 s, 50 s, etc.), the server 110 may update the task state to the state of error.

In some embodiments, one or more nodes (e.g., ROS nodes) may be added to the controller 132. The one or more nodes may perform the process for data management in the present disclosure (e.g., the process 500 in FIG. 5). In some embodiments, one node may process one task at one time. In some embodiments, if there are a plurality of nodes, part of all of the nodes may work simultaneously. In some embodiments, the node may be referred to as a remote task executor node. In some embodiments, the polling module 410, the task receiving module 420, the collection module 430, and the transmission module 440 may be implemented on at least one of the one or more nodes.

The modules in the controller 132 may be connected to or communicated with each other via a wired connection or a wireless connection. The wired connection may include a metal cable, an optical cable, a hybrid cable, or the like, or any combination thereof. The wireless connection may include a Local Area Network (LAN), a Wide Area Network (WAN), a Bluetooth, a ZigBee, a Near Field Communication (NFC), or the like, or any combination thereof. Two or more of the modules may be combined into a single module, and any one of the modules may be divided into two or more units. For example, the polling module 410 and the transmission module 440 may be combined into a single module which may both transmit a polling request to the server 110 and transmit collected data to the file server 170. As another example, the collection module 430 may be divided into two units. A first unit may obtain data based on a task. A second unit may process the obtained data.

It should be noted that the above description is merely provided for the purposes of illustration, and not intended to limit the scope of the present disclosure. For persons having ordinary skills in the art, multiple variations and modifications may be made under the teachings of the present disclosure. However, those variations and modifications do not depart from the scope of the present disclosure. For example, the controller 132 may further include a storage module (not shown in FIG. 4). The storage module may be configured to store data generated during any process performed by any component of in the controller 132. As another example, each of components of the controller 132 may correspond to a storage module, respectively. Additionally or alternatively, the components of the controller 132 may share a common storage module.

FIG. 5 is a flowchart illustrating an exemplary process for data management according to some embodiments of the present disclosure. In some embodiments, the process 500 may be implemented in the data management system 100 illustrated in FIG. 1. For example, the process 500 may be stored in a storage medium (e.g., the storage device 180, or the storage 220 of the controller 132) as a form of instructions, and can be invoked and/or executed by the controller 132 (e.g., the processor 210 of the controller 132, or one or more modules in the controller 132 illustrated in FIG. 4). The operations of the illustrated process 500 presented below are intended to be illustrative. In some embodiments, the process 500 may be accomplished with one or more additional operations not described, and/or without one or more of the operations discussed. Additionally, the order in which the operations of the process 500 as illustrated in FIG. 5 and described below is not intended to be limiting.

In 510, the controller 132 (e.g., the interface circuits 210-a and/or the polling module 410) may transmit a polling request to the server 110 to pull a task from the server 110. The task may be a remote task request. The task may be associated with obtaining, from the autonomous vehicle 130, requested data related to one or more subjects via a mobile network.

In some embodiments, the overall data set generated during the operation of the autonomous vehicle 130 may be too big to be transmitted via a mobile network. In order to obtain data related to the autonomous vehicle 130 via the mobile network, a task related to obtaining a part of the overall data (e.g., relevant and/or requested data) may be initiated.

In some embodiments, the task may include the one or more subjects and a duration of the requested data. In some embodiments, the subject may include data sources (e.g., which sensor in the autonomous vehicle 130 collects the data), the purpose of data (e.g., the data is used to detect traffic lights, the data indicates the speed of the autonomous vehicle 130), data types (e.g., text, sound, video, image, etc.), or the like, or any combination thereof. In some embodiments, the duration may be any prior time period or any future time period. For example, the start time or the end time of the duration may be a prior time point, a current time point (e.g., the time when the task is transmitted to the server 110), or a future time point.

In some embodiments, when one or more specific conditions happen, the controller 132 (e.g., the interface circuits 210-a and/or the transmission module 440) may automatically transmit a task to the server 110. For example, when the controller 132 automatically reports an error related to one or more operational issues of the autonomous vehicle 130, the controller 132 may automatically transmit a task to the server 110. Merely by way of example, when the controller 132 automatically reports an error related to detecting traffic lights, the controller 132 may automatically transmit, to the server 110, a task including one or more subjects related to detecting traffic lights and a duration of last three days. As another example, when a driver or a test engineer manually inputs an error message related to one or more operational issues of the autonomous vehicle 130 through the controller 132 (e.g., the I/O 230 of the controller 132), the controller 132 may automatically transmit a task to the server 110. Merely by way of example, when a driver or a test engineer finds that the autonomous vehicle 130 make a mistake for detecting traffic lights, the driver or a test engineer may manually input an error message related to detecting traffic lights through the controller 132. The controller 132 may automatically transmit, to the server 110, a task including one or more subjects related to detecting traffic lights and a duration of last three days.

In some embodiments, a user (e.g., a back end engineer) may input a task through the user terminal 140. The user terminal 140 may transmit the task to the server 110. For example, if the user wants to analyze the detection of traffic lights of the autonomous vehicle 130 last three days, the user may input, through the user terminal 140, a task including one or more subjects related to detecting traffic lights and a duration of last three days.

In some embodiments, when receiving a task, the server 110 may store the task information (e.g., the one or more subjects and the duration) of the task in the database server 160.

In some embodiments, the controller 132 may transmit the polling request to the server 110 continuously or at intervals (e.g., every 10 seconds, every 20 seconds, etc.). In some embodiments, the controller 132 may transmit the polling request to the server 110 when the controller 132 processes no task.

In some embodiments, considering the safety of the autonomous vehicle 130, the process for obtaining requested data based on the task would be configured so that it would not affect other operations (e.g., the operations for controlling the movement of the autonomous vehicle 130) performed by the controller 132. As a result, the controller 132 may transmit the polling request when the autonomous vehicle 130 is in a non-autonomous driving mode (e.g., a manual driving mode or a non-operating mode).

In 520, the controller 132 (e.g., the interface circuits 210-a, and/or the task receiving module 420) may receive a task from the server 110 based on the polling request.

In some embodiments, in the server 110, the tasks from the autonomous vehicle 130 and/or the user terminal 140 may be arranged in a queue in chronological order of being received by the server 110. In some embodiments, for security, the active access of the server 110 to the autonomous vehicle 130 may not be allowed. Therefore, the controller 132 may transmit a polling request to the server 110. When receiving the polling request from the controller 132, the server 110 may transmit the first task in the queue to the controller 132 in response to the polling request.

In some embodiment, when receiving a polling request from the controller 132, the server 110 may determine whether there is a task that is being processed by the controller 132 based on, for example, the state of the task. In response to a determination that there is no task that is being processed by the controller 132, the server 110 may transmit the first task in the queue to the controller 132. In response to a determination that there is a task that is being processed by the controller 132, the server 110 may not transmit any task to the controller 132.

In 530, the controller 132 (e.g., the processing circuits 210-b, and/or the collection module 430) may obtain the requested data based on the task.

In some embodiments, the autonomous vehicle 130 may generate a large amount of original data (e.g., the size of the original data may reach 1G in several minutes) during the operation of the autonomous vehicle 130. The large amount of original data may be stored in a storage medium (e.g., the storage device 180, and/or the storage 220 of the controller 132) of the autonomous vehicle 130.

The original data generated during the operation of the autonomous vehicle 130 may be marked with one or more subjects and a timestamp. The controller 132 may collect the requested data by comparing the subject in the task with the subject of the original data and comparing the duration in the task with the timestamp of the original data.

In some embodiments, if the end time of the duration in the task is a future time point, the controller 132 may wait for the future time point to obtain the requested data.

In some embodiments, the controller 132 may further process the collected data. Merely by way of example, the controller 132 may compress the collected data (e.g., images and/or videos) that is from computer vision (e.g., cameras) in the autonomous vehicle 130. In some embodiments, the processing instruction may be included in the controller 130. For example, after collecting the original data based on the task, the controller 132 may automatically perform the compression instructions to compress the collected data (e.g., images and/or videos) that is from computer vision (e.g., cameras). In some embodiments, the task may include the processing instructions. For example, after collecting the original data based on the task, the controller 132 may compress the collected data (e.g., images and/or videos) that is from computer vision (e.g., cameras) based on the compression instructions in the task.

In 540, the controller 132 (e.g., the processing circuits 210-b, and/or the transmission module 440) may transmit the requested data to the file server 170 via the mobile network. In some embodiments, after receiving the requested data from the autonomous vehicle 130, the file server 170 may transmit the storage location of the requested data to the server 110. Alternatively, after receiving the requested data from the autonomous vehicle 130, the file server 170 may transmit the storage location of the requested data to the controller 132. The controller 132 may transmit the storage location to the server 110. The server 110 may transmit the storage location of the requested data to the user terminal 140, directing the user terminal 140 to display the storage location.

In some embodiments, the file server 170 may permanently store the requested data. In some embodiments, the file server 170 may delete the requested data after a period of time (e.g., 1 week, 2 weeks, 1 month, etc.).

In some embodiments, the server 110 may update the state of the task based on the condition the task is in. The state of the task may include a state of waiting, a state of running, a state of done, and a state of error. The state of waiting indicates that the task is waiting for being processed by the controller 132 in the server 110. The state of running indicates that the task is being processed by the controller 132. The state of error indicates that there are one or more errors during processing the task and the process for processing the task is terminated. The state of done indicates that the task has been done by the controller 132 (e.g., the controller 132 has transmitted the requested data to the file server 170). In some embodiments, when the task queues in the server 110 to wait for being transmitted to the controller 132, the server 110 may mark the task with the state of waiting. When the task is transmitted to the controller 132, the server 110 may update the task state to the state of running. If the waiting time of the task in the server 110 is longer than a waiting time threshold (e.g., 10 minutes, 20 minutes, 30 minutes, etc.), the server 110 may update the task state to the state of error.

In some embodiments, the controller 132 (e.g., the interface circuits 210-a and/or the transmission module 440) may transmit the state of the task to the server 110 during the collection of the data. For example, because the requested data is transmitted through a mobile network, there may be a limitation to the size of the requested data. If the size of the requested data is larger than a size threshold (e.g., 10M, 20M, 30M, 50M, etc.), the controller 132 may transmit a message indicating that the task is in the state of error to the server 110. The server 110 may update the task state to the state of error based on the message. As another example, if the duration for obtaining the requested data is longer than a duration threshold (e.g., 10 s, 20 s, 30 s, etc.), the controller 132 may transmit a message indicating that the task is in the state of error to the server 110. The server 110 may update the task state to the state of error based on the message. As still another example, when the controller 132 transmits the requested data to the file server 170, the controller 132 may transmit a message indicating that the task is in the state of done to the server 110. The server 110 may update the task state to the state of done based on the message. As further another example, when the controller 132 does not transmit, to the server 110, a message indicating the state of the task (e.g., the state of error or the state of done) during the obtaining of the requested data in a predetermined period of time (e.g., 30 s, 40 s, 50 s, etc.), the server 110 may update the task state to the state of error.

In some embodiments, after marking and/or updating the state of the task, the server 110 may transmit the marked and/or the updated state to the database server 110 to store the marked and/or the updated state.

In some embodiments, if the task is in the state of error or the state of done, the server 110 may remove the task from the queue. In some embodiments, for security, the server 110 may transmit the latest state of the task to the user terminal 140 in response to a polling request from the user terminal 140, instead of actively access the user terminal 140 to transmit the state of the task. The user terminal 140 may display the latest state of the task (e.g., through the display 320). In some embodiment, along with the latest state of the task, the server 110 may transmit the reason that causes the state of the task. For example, if the waiting time of the task in the server 110 is longer than the waiting time threshold, the server 110 may update the task state to the state of error. When receiving the polling request from the user terminal 140, the server 110 may transmit, to the user terminal 140, the state of error and a message indicating that the waiting time of the task in the server 110 is longer than the waiting time threshold. In this way, the users may monitor the task. In some embodiments, the users may delete or resend, through the user terminal 140, the task that is in the state of error. In some embodiments, the users may delete, through the user terminal 140, the task that is in the state of waiting. In some embodiments, if the task is in the state of running, the task may not be deleted by the server 110 or the users.

In some embodiments, when the controller 132 works well again after a break-down or when the controller 132 restarts up during processing the task, the task may be still in the state of running. When the controller 132 transmits a polling request to the server 110, the server 110 may first send the task to the controller 132.

In some embodiments, the user terminal 140 may transmit the polling request to the server 110 continuously or at intervals (e.g., every 10 s).

In some embodiments, the controller 132 may process one task at one time. In some embodiments, the controller 132 may process more than one task simultaneously.

In some embodiments, one or more nodes (e.g., ROS nodes) may be added to the controller 132. The one or more nodes may perform the process 500 for data management. In some embodiments, one node may process one task at one time. In some embodiments, if there are a plurality of nodes, part of all of the nodes may work simultaneously. In some embodiments, the node may be referred to as a remote task executor node.

The process for data management in the present disclosure may efficiently and safely transmit remote requested data because the controller 132 pulls a task from the server 110 based on a polling request and transmit the requested data based on the task, instead of users actively accessing the autonomous vehicle 130 to obtain the requested data through a virtual private network (VPN), and because the requested data may be transmit to the file server 170 via a mobile network in the autonomous vehicle a relatively short time after the task is transmitted to the server 110, instead of waiting for more than 1 week to get the requested data by delivery.

It should be noted that the above description is merely provided for the purposes of illustration, and not intended to limit the scope of the present disclosure. For persons having ordinary skills in the art, multiple variations and modifications may be made under the teachings of the present disclosure.
